The AirTAC Airtac GAF Air Filters GAF600C25AG is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 40 µm, protecting downstream valves and tools. It has 1" ports and a 205 cc drain bowl. It is a filter only — it does not regulate or set pressure.
The AirTAC GAF600C25AG is a compressed air filter for 1in lines with G thread. A diversion structure spins the incoming air so liquid water and solid particles are thrown outward into the drain bowl, while the HDPE element catches the finer grain at a 40 um filtering grade. This is the largest body in the GAF range: a 205 cc metal drain bowl, a 1040 g mass and a flow curve plotted to 12000 L/min. Rated 0.15-0.9 MPa (20-130 psi) and -5 to 70 C, it keeps downstream cylinders, valves and tools clear of condensate and grit. It cleans the air only; pressure setting is not part of its job.

Specifications follow the official AirTAC GAF catalogue (pages 225-226). Air must not freeze in the unit. This is a filter only — it separates water and solid particles but does not set or hold a downstream pressure. To regulate pressure as well, use the matching GAFR600 filter-regulator.

A GAF has no regulator and no pressure gauge — there is no type, gauge or reflux code. Need to regulate pressure too? The matching GAFR600-25 is the same filter with a built-in regulator.
Figures are the end of the flow curve plotted in the AirTAC catalogue — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. A filter this size drops less pressure at flow than the same-body GAFR filter-regulator, so match it to your peak demand.

Feeding a 1in shop-floor header, the 205 cc bowl and the 12000 L/min curve envelope let this filter sit right where the main line branches toward workstations, catching scale and condensate before they spread.
One unit at the drop point can serve several concurrently running stations, so actuated clamps and air tools keep working even when the compressor room pulls in humid summer air.
Installed on the line leaving the compressor room, the automatic drain clears accumulated water without a daily walk-around, which matters on long runs in unattended plant areas.
Pick the 1in port when a machine header or a multi-branch supply main needs the largest GAF body; one step down, the GAF500 takes a 3/4in port with a 108 cc bowl and a curve plotted to 9000 L/min. The C in the code locks the bowl to metal, the only material offered on the GAF600, so confirm compatibility with the supplier if aggressive surroundings are expected. The A option means an automatic drain that empties collected condensate on its own, well suited to wet or unattended lines, and a mounting bracket is included in the box. The element here is the standard 40 um grade; the W suffix would swap in a 5 um core for finer filtration at a higher service burden. The G suffix sets the port thread standard to G, so order fittings to match. If the line also needs a controlled pressure, the matching GAFR600 body combines filtration with regulation in a single housing. The 205 cc drain bowl holds about 8x the condensate of the GAF200's 25 cc bowl, so draining rounds can be stretched far apart on the same wet line.
Quick checklist
This is a filter only — it removes water and solid particles but adds no pressure control and no lubrication. Add a GAR regulator, a GAL lubricator, or step up to the GAFR600-25 filter-regulator as your air-prep needs grow.
Filtering grade 40 um with an HDPE element, working pressure range 0.15-0.9 MPa (20-130 psi), proof pressure 1.5 MPa (215 psi), operating temperature -5 to 70 C, drain bowl 205 cc in metal, weight 1040 g, port 1in with G thread and an automatic drain. The flow curve is plotted to 12000 L/min.
This GAF is a filter only: it spins water and dirt into the bowl and traps fine particles, but it does not set, regulate or hold downstream pressure in any way. The GAFR600 belongs to the same family and adds a built-in pressure regulation section; order that body instead whenever a controlled outlet pressure is required.
